Abstract (en)
[origin: WO9940156A1] Alkylene oxide polymer compositions having particular molecular weight distributions are disclosed. As a result of the molecular weight distributions, the disclosed alkylene oxide polymer compositions are suitable, among other things, for the manufacture of films, e.g., for use in manufacturing soft gel capsules. Capsules made from the disclosed alkylene oxide polymer compositions can provide enhanced resistance to crosslinking often caused by liquid filling materials, e.g., polyethylene glycol, used in gelatin capsule manufacture.
